Tonight Melissa and I went to see the movie "An Inconvenient Truth".
This is a great movie that presents the scientific facts and shows how we are impacting the planet.

(And then ultimately opted to go to film school for my degree.) Anyway, I feel compelled to do my part to reduce carbon dioxide. I'm going to get that Mercedes. Even though I haven't driven it yet, I have a good feeling about it.
